The Devil Horse is a 1932 American Pre-Code movie serial starring Harry Carey, Frankie Darro and Noah Beery, Sr. that was distributed by Mascot Pictures. This is regarded as the best of the three serials Harry Carey made in the early 1930s, the other two being Last of the Mohicans and The Vanishing Legion. Frankie Darro had co-starred with Carey previously in The Vanishing Legion. Lane Chandler played the murdered ranger Elliott Norton, uncredited.

Plot
Hank Canfield (Noah Beery), leader of a gang of horse thieves, attempts to steal a wild racehorse called El Diablo. The crooks bungle the job, but in making their escape, they kill a Ranger named Elliott Norton (Lane Chandler). The ranger’s older brother Bob (Harry Carey) sets out to bring his brother’s killers to justice, not realizing the apparently respectable Canfield is the guilty party. A young mute orphan referred to as the Wild Boy (Frankie Darro) is the only one in town who knows who the killer is, and Bob Norton attempts to communicate with the child to draw the secret out of him. Meanwhile, the horse thieves make further attempts to kidnap the prized racehorse.
